Science
Mechanism of Action
This ingredient operates through a dual-action pathway: physically, its high surface area absorbs excess sebum and moisture while providing a 'ball-bearing' effect for superior spreadability; biologically, it facilitates 'ion therapy' by slowly releasing silicate and magnesium ions that support fibroblast activity and structural skin regeneration.
Research
Clinical Evidence
Medium confidence1%
Key findings
- 01 Demonstrated stimulation of human dermal fibroblast adhesion and proliferation via silicon ion release at 1.0 mg/mL.
- 02 Identified as a safe narrowband UVB emitter (314 nm) for targeted skin rejuvenation and inflammatory condition management at 0.09 mol%.
Transparency
Dusting Analysis
Often included at very low concentrations purely for opacifying or anti-caking purposes; however, concentrations near 1% are required to unlock its bioactive regenerative potential.
The Formula
Formulation
Stability
Highly resilient in neutral to alkaline environments where it can serve as a pH buffer. It is technically insoluble but disperses evenly in both oil and water phases.
Synergies
- Mineral-based UV filters
- Mattifying polymers
- Hydrophilic humectants
Conflicts
- Strong acids (leads to silica decomposition)
- Cationic surfactants
- High electrolyte concentrations
Safety
Safety Profile
Must be certified non-fibrous and asbestos-free. Max concentration varies by application type, peaking at 26.3% in specific cosmetic categories.
